Marine Corps composite system
The Marines use 4 composite scores — GT, CL, EL, MM — computed by USMC from your ASVAB subtests. Each is roughly centered at 100 with most MOS requiring 90+ for entry-level and 105-115+ for technical roles.
- GT (General Technical): Word Knowledge + Paragraph Comprehension + Arithmetic Reasoning. Drives most infantry, intel, admin, and command MOS.
- CL (Clerical): Word Knowledge + Paragraph Comprehension + Mathematics Knowledge. Administrative, postal, supply roles.
- EL (Electronics): General Science + Arithmetic Reasoning + Mathematics Knowledge + Electronics Information. Aviation electronics, comms, avionics maintenance.
- MM (Mechanical Maintenance): Auto and Shop + Mechanical Comprehension + Electronics Information. Aircraft mechanic, ground equipment, support.
High-value Marine Corps MOS for transition
- Intel (0231, 0241, 0261, 0211): GT≥110 required. Strong civilian intelligence community / contractor crossover.
- MARSOC Critical Skills Operator (0372): GT≥105 plus selection assessment. Highly competitive elite SOF.
- Aviation Maintenance (6212-6288): MM≥105 required. FAA A&P licensing pathway after service.
- Avionics (63xx, 64xx): EL≥105+. Strong civilian aviation electronics market.
- UAV/UAS Operator (7314): GT≥110. Growing civilian drone / autonomous systems industry.
- Air Traffic Control (7251): GT≥110. FAA ATC pipeline with veterans' preference.
Marines vs other services on ASVAB
Marine Corps minimum AFQT is 35 — slightly higher than the other services' 31 (HS diploma). This is a deliberate USMC retention preference: somewhat higher screening at entry yields stronger sustainment and retention through the first contract.
MOS prerequisites tend to be a bit higher than Army equivalents (e.g., 0311 Rifleman = GT 90 vs Army 11B = CO 87 with similar subtest mix). For aviation, USMC and Navy share many maintenance and avionics standards because Marine aviation falls under Navy logistical systems.
